Higher number of Helicobacter pylori CagA EPIYA C phosphorylation sites increases the risk of gastric cancer, but not duodenal ulcer

Autor: Oliveira Rodrigo C, Cabral Mônica MDA, Saraiva Ivan EB, Rocha Andreia MC, Rocha Gifone A, Batista Sérgio A, Queiroz Dulciene MM

Publikováno v: BMC Microbiology, Vol 11, Iss 1, p 61 (2011)

Abstract Background Helicobacter pylori infection is one of the most common infections worldwide and is associated with gastric cancer and peptic ulcer. Bacterial virulence factors such as CagA have been shown to increase the risk of both diseases. S

Allelic diversity and phylogeny of homB, a novel co-virulence marker of Helicobacter pylori

Autor: Yamaoka Yoshio, Ménard Armelle, Cordeiro Rita, Oleastro Mónica, Queiroz Dulciene, Mégraud Francis, Monteiro Lurdes

Publikováno v: BMC Microbiology, Vol 9, Iss 1, p 248 (2009)

Abstract Background The homB gene is a Helicobacter pylori disease-marker candidate, strongly associated with peptic ulcer disease, while homA, its paralogue gene with 90% sequence identity, is correlated with non-ulcer dyspepsia. The HomB encoded ou

Disease association with two Helicobacter pylori duplicate outer membrane protein genes, homB and homA

Autor: Oleastro Monica, Cordeiro Rita, Yamaoka Yoshio, Queiroz Dulciene, Mégraud Francis, Monteiro Lurdes, Ménard Armelle

Publikováno v: Gut Pathogens, Vol 1, Iss 1, p 12 (2009)

Abstract Background homB encodes a Helicobacter pylori outer membrane protein. This gene was previously associated with peptic ulcer disease (PUD) and was shown to induce activation of interleukin-8 secretion in vitro, as well as contributing to bact
